Two more Miss America winners are joining current titleholder Cara Mund in her protest against the organization — and calling for the resignation of its leadership.

As the Post reported, Lund penned an open letter last week claiming that she’d been sidelined and demeaned by the controversial new leadership of Miss America, which includes news personality and former winner Gretchen Carlson.

Now we’re told former Miss Americas Suzette Charles and Heather Whitestone are going on NBC’s “Megyn Kelly Today” on Monday to back Mund.

We’re told the pair — who are among several former title holders to put their name to a petition calling for leadership changes — will “share behind-the-scenes details of the pageant and why they’re pushing for change.”
